Problems solved by technology

[0002] At present, the pinellia seedlings sold in the market are mainly wild seedlings purchased from other places, and some of them are seedlings with a diameter of less than 10 mm left after the harvest of pinellia planted in different places in the previous year. Prominent problems such as mixed quality, lack of good varieties, infestation by diseases and insect pests, and continuous cropping obstacles have seriously affected the yield and quality of Pinellia medicinal materials. The shortage of high-quality seed stems has become a bottleneck restricting the development of pinellia industry
[0003] The patent CN109804914A "A Soilless Floating Seedling Technology of Pinellia" in the prior art mentioned the use of seedling trays for floating seedlings, but the environment was not further controlled, resulting in low yields of hydroponic pinellia, which still cannot Solve the problem of high yield in hydroponic pinellia

Embodiment 1

[0075] Step 1, cultivate Pinellia seed stems:

[0076] Wild or domestic robust Pinellia bulbs were collected, cleaned and disinfected, and then inoculated on MS+6-BA2.0mg / L+NAA1.0mg / L+white sugar 30.0g / L+agar 6.0g / L medium for one step Seedling culture, culture temperature 22-25 ℃, pH 5.8-6.0, illuminance 3000Lx, light 12h / d, after culturing for 100-120 days, continue to transfer and expand the culture, and the culture conditions are the same as above. The cultivated tissue culture Pinellia seed stems were collected, washed and dried for later use.

[0077] Step 2, water cultivation of seedlings:

[0078] Select high-quality seed bulbs with a particle size larger than 10mm without damage and mildew, soak them in 2% carbendazim powder suspension for 15 minutes, remove them to dry, and plant them in a planting basket with a diameter of 55mm, The height of 60mm, the depth of planting is 30mm, and the plant is planted with ceramsite with a diameter of 10mm. Each planting basket ...

Embodiment 2

[0088] Step 1, cultivate Pinellia seed stems:

[0089] Collect wild or domestic healthy seeds, wash and sterilize them, then inoculate them on MS+6-BA1.0mg / L+NAA0.5mg / L+white sugar 30.0g / L+agar 6.0g / L medium for one-step seedling culture , culture temperature 22~25℃, pH 5.8~6.0, illuminance 3000Lx, illumination 12h / d, after culturing for 100~120 days, continue to transfer and expand the culture, and the culture conditions are the same as above. The cultivated tissue culture Pinellia seed stems were collected, washed and dried for later use.

[0090] Step 2, water cultivation of seedlings:

[0091] Select high-quality seed bulbs with a particle size larger than 10mm without damage and mildew, soak them in 2% carbendazim powder suspension for 15 minutes, remove them to dry, and plant them in a planting basket with a diameter of 55mm, The height of 60mm, the depth of planting is 30mm, and the plant is planted with ceramsite with a diameter of 10mm.

Abstract

The invention belongs to the field of seedling cultivation, and relates to a method and device for high-yield cultivation of pinellia seedlings through hydroponic cultivation, through the steps of cultivation of pinellia seedlings, water cultivation of seedlings, harvesting, water cultivation of seedlings again, etc., to realize hydroponic high-efficiency production of pinellia seedlings . The hydroponic method of the present invention realizes the three-dimensional multi-layer planting and high-efficiency breeding of pinellia seedlings under controllable environmental conditions and automatic control of light and nutrient solution circulation.

Description

technical field [0001] The invention belongs to the field of seedling cultivation, and particularly relates to a method and a device for high-yield seedling cultivation in hydroponics of Pinellia ternata. Background technique [0002] At present, the Pinellia seedlings sold in the market are mainly wild seed stems purchased in different places, and some of them are seed stems with a diameter of less than 10mm remaining after the harvest of Pinellia ternata planted in different places in the previous year. Prominent problems such as mixed quality, lack of high-quality varieties, infestation by pests and diseases, and continuous cropping obstacles have seriously affected the yield and quality of Pinellia sinensis. [0003] In the prior art, the patent CN109804914A "A Soilless Floating Seedling Raising Technology of Pinellia ternata" applied by You Jingmao et al. mentioned the use of seedling trays to carry out floating seedling raising, but the environment was not further cont...
